  • Patent number: 9976668
    Abstract: A valve directs fluid flow received from a device to one of a heater and a cooler. The valve includes a spool movably disposed in the housing between a first, second, and third position. An actuator is in fluid communication with the fluid. The actuator includes a smart material that deactivates when the fluid temperature is no greater than a first temperature, partially activated when the fluid temperature is greater than the first temperature, and fully activated when the fluid temperature is at least equal to a second temperature. The spool moves to the first position when deactivated and fluid flows from the cavity, to the heater. The spool moves to the second position when partially activated to prevent fluid from flowing to each of the heater and the cooler. The spool moves to the third position when fully activated and fluid flows from the cavity, to the cooler.

  • Patent number: 9957771
    Abstract: A status assembly to provide visual and electronic indication of the position (open, closed, in-between) of the ram of a ram-type blowout preventer (BOP). The assembly is capable of coupling with a hydraulic motor that can be used to open and close the ram locks. The status assembly includes a rotatable element protruding from the BOP, a gear rotatable by the rotatable element, and an indicator that indicates the rotation position of the rotatable element and thus the linear position of the BOP ram. Some embodiments can also include a sensor that outputs an electronic signal to the system operator and can be incorporated into the main display for the BOP control system. This device is able to give immediate feedback to operators and to indicate whether each ram has achieved its intended travel.

  • Patent number: 9939077
    Abstract: A fluid circuit includes a device, a cooler, and a valve. The valve includes a housing, a sealing member, a biasing device, and an actuator. The sealing member moves inside the housing between a first position and a second position. The actuator includes a smart material that is activated when the temperature of a fluid inside the housing exhibiting at least a first temperature, causing the sealing member to move to the second position. The smart material is deactivated when the fluid is a sufficient number of degrees less than the first temperature, causing the sealing member to move to the first position. The fluid flows from the housing to the device and then to the housing when the sealing member is in the first position. The fluid flows from the housing to the cooler and then to the device when the sealing member is in the second position.

  • Patent number: 9919689
    Abstract: Venturi devices are disclosed that have a housing defining a conduit having a Venturi gap. Downstream of and bypassing the Venturi gap is a bypass check valve that defines an internal cavity having a first seat, a second seat, an inlet port, at least two outlet ports, and a seal member seated therein that is translatable between a closed position against the first seat and an open position against the second seat. The two outlet ports of the bypass check valve enter the conduit at opposing positions disposed a distance from a top of the conduit, which is located at a midsagittal plane of the housing. Further, a transition from a tapering section downstream of the Venturi gap and upstream of each of the two outlet ports to a discharge section downstream of the two outlet ports forms a gradually, continuously tapering interior surface of the conduit.

  • Patent number: 9915371
    Abstract: Provided is a hydraulic valve including a valve body having a first port, a second port, and a pilot port, and a piston movable in the valve body to an open position by a pilot pressure flowing through the pilot port that acts on a portion of the piston to move the piston away from a valve seat in the body to allow fluid flow between the first and second ports. The piston is then movable to the closed position by a resilient member in the absence of the pilot pressure. In this way, during an event such as a power failure of a vehicle when the pilot pressure is unavailable, the valve is closed to prevent fluid draining from a hydraulic function to prevent movement of the function without using a mechanical locking device.
